In my spare time, I write science fiction. This started out rather late in life (compared with most writers, who've had stories bubbling out of their heads since they could string sentences together) so I've always felt a bit of a fraud. But I'm slowly gaining confidence to think that, in fact, I am not a bad writer.
This is a warming, but fragile, realisation.
For this I can thank the harsh but supportive groups of critiquers who've helped me develop my skills. Their comments have evolved over the years from outright ripping-apart, to glimmers of serious encouragement.
Being able to string words into stories is a great gift.
